24.05.0

24.05.0 / 2024-05-20 Release

📌 Highlights of this major release include:

• Harvest supports consistency groups (CG) in the SnapMirror dashboard. Thanks to @Nikhita-13 for reporting this.

• We've fixed an intermittent latency/ops spike problem caused by Harvest incorrectly handling ONTAP partial aggregation. This impacted all perf objects. A big thank you to @summertony15 for reporting this critical issue.

• Harvest dashboards are compatible with Grafana 10.x.x versions.

• 💎 LUN, Flexgroup and cDot dashboard updated to work with FSx. Some panels are blank because FSx does not have that data.

• The credentials script supports providing both username and password. Thanks to @kbhalaki for reporting.

• Harvest configuration file supports reading parameters from environment variables. Kudos to @wally007 for the suggestion.

• Harvest includes remediation steps for EMS alerts.

• 💎 New Dashboards:

  • NFS Troubleshooting which provides links to detailed dashboards. Thanks to RustyBrown for contributing these.
  • Detailed Dashboards: Volume by SVM and Volume Deep Dive.

• 🚀 Performance Improvements:

  • Rest/RestPerf Collector only requests metrics defined in templates, reducing API time, payload size, and collection load.
  • TopK queries in dashboards are now faster. Thanks to AlessandroN for reporting.

• ⭐ Several of the existing dashboards include new panels in this release:

  • Workload dashboard includes adaptive QoS used percentage tracking. Thanks to @faguayot for reporting.
  • Network dashboard includes ethernet errors. Thanks to Rusty Brown for contributing.
  • Node dashboard includes the BMC firmware version. Thanks to @summertony15 for reporting.
  • SVM dashboard now includes NFS4.2 panels. Thanks to Didlier for reporting.
  • The Volume dashboard includes several new panels:
    • Volume growth rate panels. Thanks to AlessandroN for reporting.
    • I/O density panels. Thanks to @jgasher for reporting.
    • Volume capacity forecasting panels, predicting a volume's used sized over the next 15 days. Thanks to @s-kuchi for reporting.

• 🌾 Harvest includes a new template to collect lock counts at the node, SVM, LIF, and volume levels.. Thanks to @troysmullerna for reporting.

• 📕 Documentation Additions:

  • How to customize Prometheus's retention period in a Docker deployment. Thanks to @WayneShen2 for the suggestion.
  • How to use endpoints in a REST collector template. Thanks to Hubert for reporting.
  • Harvest includes remediation steps for EMS alerts.
  • How to use confpath to extend templates.

• Harvest supports embedded exporters in Harvest configuration. This means you can define your exporters in one place instead of multiple. Thanks to @wagneradrian92 for reporting.

• Harvest supports exporting to multiple InfluxDB instances. Thanks to @figeac888 for reporting.

• Node label metrics include HA partner details. Thanks to @johnwarlick for reporting.

Announcements

‼️ IMPORTANT Release 24.05 removes duplicate quota metrics. If you wish to enable them, refer here.

💡 IMPORTANT After upgrading, don't forget to re-import your dashboards to get all the new enhancements and fixes. You can import them via the 'bin/harvest grafana import' CLI, from the Grafana UI, or from the 'Maintenance > Reset Harvest Dashboards' button in NAbox.

Known Issues

• ⚠️ Harvest does not calculate power metrics for AFF A250 systems. This data is not available from ONTAP via ZAPI or REST. See ONTAP bug 1511476 for more details.
• ⚠️ ONTAP does not include REST metrics for offbox_vscan_server and offbox_vscan until ONTAP 9.13.1. See ONTAP bug 1473892 for more details.

IMPORTANT 7-mode filers that are not on the latest release of ONTAP may experience TLS connection issues with errors like tls: server selected unsupported protocol version 301. This is caused by a change in Go 1.18. The default for TLS client connections was changed to TLS 1.2 in Go 1.18. Please upgrade your 7-mode filers (recommended) or set tls_min_version: tls10 in your harvest.yml poller section. See #1007 for more details.
